METALLIC LINK FABRIC.

Specification of Letters Patent.

Patented Mar. 1,2, 1912..

Application filed .Tune 2, 1911. Serial No. 630,885.

To all whom it may concern:

Be it known that l, J oser PnJoi-IAR, a citizen of the United States,and residentl of the cit-y of New York, in the county of Kings and Stateof New York, have invented certain new and useful Improvements inMetallic Link Fabrics, of which the following is a specification.

The present invention relates to a metallic link fabric for bed bottoms,wire fences and other purposes, and has for its object to produce afabric consisting of connected links, preferably metallic, which is veryflexible, and uniform in character throughy out.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in thecombination, arrangement and construction of parts hereinafter' fullydescribed, pointed out in the appended claims and illustrated in theaccompanying drawings, it being understood that many changes may be madein the size and proportion of the several parts and minor details ofconstruction without departing from the spirit or sacrificing any of theadvantages of the invention.

A few of the many possible embodiments of the invention are illustratedin the accompanying drawings, in which Figure 1 is a plan view of aflexible link fabric made in accordance with the present invention;Figs. 2 and 3 are plan views of units composing the fabric; Fig. 4 is aside elevation of the element shown in Fig. 3; Fig. 5 is a plan view ofa modification; Figs. 6 to 8, inclusive, similar views of unitscomposing this modiiied fabric; Fig. 9 is a plan view of anothermodification; Figs. 10 to 12, inclusive, similar views of unitscomposing the modification shown in Fig. 9; Fig. 13 is a plan view of afurther modification; Figs. 14 to 16, inclusive, similar views of unitscomposing this further modification; Fig. 17 is a plan view of a stillfurther modiication; and Figs. 18 to 21, inclusive, similar views ofunits composing the fabric shown in Fig. 17.

Broadly speaking, the fabric forming the subject matter of the presentapplication for Letters Patent comprises two series of units, one seriesbeing ring shaped, and the other series comprising links whichinterconnect the ring shaped units.

Referring now more particularly to Figs.

indicate suitable 1 to 4, inclusive, the numerals 22 ring shaped unitsmade of any metal and size, according to the requirements. These unitsare arranged in rows 23, and connected by links 24 in the form of,preferably, metallic strips, provided with two perforations 25, whichare engaged by two adjacent rings 22. The rows so formed are connectedby links 2G, the construction of which is exactly that of the links 24,and each of which is engaged by two rings 22 of two adjoining rows 23.It will be observed that this forms a simple and substantialconstruction, and one which is easy to make and assemble since for thebody of the fabric there are only two kinds of parts, that is the ringsand the links. The links interconnect the rings of the fabric securelyand uniformly, while giving a great flexibility. It is to be noted thatthe rings are held by the links 24 and 26, respectively, at givendistances in their plane, but are permitted to move out of this plane byreason of their being pivotally connected, as it were, through theintermediary of the links 24 and 26. Obviously these pivot likeconnections make the fabric flexible.

The fabric shown in Fig. 5 of the drawings possesses even greaterflexibility than that shown in Fig. 1. This fabric comprises a pluralityof ring shaped units 27, which are arranged in rows 28 and 29. The unitsof the rows 2S are connected by chain links 30, and those of the rows 29by strips 31, each having two perforations 32, engaged b v two adjacentrings of a row. The rows 28 and 29 are arranged alternately and formchains, as it were. These chains are interconnected by metallic strips33, similar in construction to the strips 31, and by chain links 34',the strips 33 and the links 34 being arranged in alternating rows whichrun at right angles to the axes of the chains mentioned. It will beobserved that while in a general way the rings of the fabric are held atpredetermined distances by the metallic strips 31 and 33, the connectingchain links 30 and 34 will render the fabric more flexible than thatshown in Fig. 1 of the drawings.

Another modification of the fabric is shown in Fig. 9 of the drawings,and comprises ring shaped units 34, which are arranged in rows 35, theunits of said rows being connected by chain links 36, forming thereby aplurality of chains. These chains are interconnected by metallic strips37, having perforations 38, which are engaged by two adjacent rings 34of two neighboring rows. Each ring is engaged by two strips 37. In thisconstruction the rows 35 are kept at predetermined distances by thestrips 37, the units of the rows 35 being allowed to move freely towardeach other, the chain links 36 permitting of such movement.

A further modification is shown in F ig. 13 of the drawings, in whichtwo series of rings are made use of, one series being denoted by thenumeral 39 and the other by the numeral 40. The smaller rings 40 arearranged concentrically with the rings 39 in rows 41. The units of therows are connected by metallic strips 42, having four perforations 43,which are engaged by two adjacent rings 39 and those rings 40 which areconcentrically arranged within the larger rings. The rows 41 areinterconnected by metallic strips 44, similar in construction to thestrips 42. The strips 44 eX- tend in directions at 60O to the strips 42,whereby a hexagonal pattern is formed, each ring being engaged by siXstrips 42 and 44, respectively. By means of this construction the twoseries of rings 39 and 40 are kept at predetermined distances, themovement of the rings 39 toward and away from each other being alsolimited by the metallic strips.

A still further modification is'shown in Fig. 17 of the drawings, whichcomprises also two sets of ring shaped units 45 and 46, which arearranged concentrically with each other and held in such concentricpositions by metallic strips 47, having each two perforations 48,engaged by two concentric rings 45 and 46. The rings are arranged inrows 49, the units of the rows being connected by chain links 50,cachengaging two adjacent ring sets 45 and 46. The rows 49 areinterconnected by chain links 51, whereby the ring sets of the vfabricare permitted to move toward and away from leach other a limiteddistance, while the two rings of each set are held in their concentricpositions by the strips 47.

What I claim is:

1. In-a metallic fabric, the combination with a plurality of ring shapedunits arranged in rows, of perforated strips connecting the adjacentunits of each row, and perforated strips connecting the adjacent unitsof adjoining rows.

2. In a metallic fabric, the combination with a series of ring shapedunits arranged in rows, of a second series of ring shaped units locatedconcentrically with said first series, perforated strips connecting theadjacent units of said rows and holding said two series of units inconcentrical, relation to each other, and perforated strips connectingthe units of adjoining rows.

Signed at New York, in the county of New York and State of New York this29th day of May, A. D. 1911. JOSEF PEJ CHAR.
